ABSTRACT:
A blast nozzle is provided for cleaning a surface with a blast media which is softer and more friable than sand such as sodium bicarbonate and which comprises an inlet section which contains a passageway which converges substantially along only one planar axis to a rectangular venturi orifice and a fan-shaped outlet section which contains a passageway which diverges along substantially only one planar axis perpendicular to the planar axis of convergence of the converging passageway, the inlet passageway being greater than twice the diameter of the inlet of the nozzle so as to provide streamlined flow and reduce turbulent flow of the friable blast media in the blast nozzle. The passageways in the blast nozzle are formed by opposed modular structures which are releasably secured to the nozzle and can be changed to change the length and angle of convergence and expansion ratio of the nozzle.
